eVenn (version 2.1.6)

eVenn-package: eVenn: A powerful tool to quickly compare huge lists by Venn diagrams.

Description

Compute a matrix comparison of lists (from 2 to infinite) and plot the results in a Venn diagram if (N

Details

ll{ Package: eVenn Type: Package Version: 2.1.6 Date: 2011-07-12 License: GPL LazyLoad: yes } The lists to be compared must be alone in a folder (path_lists). The lists can be just identifiers lists or be lists of genes with annotation columns and data columns. The option "annot" (T/F) allow to produces a result "counts" file with a venn diagram matrix (0/1) and the corresponding annotations and data. The first column of the data files must be the unic identifiers, it is used by eVenn to detect common or specific genes. v2.1.6: Allow to compare list of matrix (matLists) and use eVenn like a function (FilesOut=FALSE). v2.1.3: Package evolution compatibilitie (R 2.14). v2.1.2: Reported bugs corrections. v2.1.1: Graphical improvement. v2.1: Add the Venn proportional option and correct reported bugs. v1.2: eVenn can separate up and down regulated genes. v1.1: No other library called. Lists types can be mixed, (columns numbers, file types) The total number of unic genes/IDs is printed in the graph. New column "Total lists" in the results files indicating the nbr of lists in which each ID is found.
